I need help with modding

H20Element

Ok, so I thought of modding GTA V single player recently and I need help with it. I know how to install mods and such, but If I want to play online I'd have to remove the mods. Is there a way of doing it in a way that will be safe when entering online? Cus, I don't want to hop on online and forget something just to get banned in the end. Any help is appreciated.
